WATER-MOTOR.

Specification of Letters Patent.

Patented Dec. 3, 1912.

To all whom it may concern Be it known thatI, ALFRED SHIELDS, a citizen of the United States, residing at Vicksburg, in the county of Warren and State of Mississippi, have invented certain new and useful Improvements in VVater- Motors, of which the following is a specification.

This invention relates to improvements in water motors, and particularly to improved structures which will utilize the pressure of water in flowing streams without necessarily providing dams or the like for directing the water toward the motor.

The object in view is the arrangement of an improved structure formed with one or more reciprocating blades adapted to receive the pressure of water in both its forward and rearward movement for transmitting power to any desired device.

A further object of theinvention is the arrangement of a plurality of blades mounted in pairs and designed to operate in opposite directions at the same time, the blades being arranged either vertical or horizontal, and automatically shifted upon the extreme movement of the respective blades so that the blades will automatically move back and forth under the pressure of the water of a moving stream.

Vith these and other objects in view the invention comprises certain nove-l constructions, combinations, and arrangement of parts as will be hereinafter more fully described and claimed.

In the accompanying drawings: Figure 1 is a side elevation of an embodiment of the invention, certain parts being broken away for clearly disclosing the construction. Fig. 2 is a front view of the structure shown in Fig. 1. Fig. 3 is a top plan view of the structure shown in Fig. 2. Fig. 4 is an enlarged detail fragmentary sectional view through a clamping member embodying certain features of the invention. Fig. 5 is a perspective view showing means of securing the guides to the blades.

In constructing a motor embodying the invention the same may be arranged tooperate vertically, as shown in Figs. 1 to 3 inclusive, or constructed to operate horizontally. A suitable framework is provided in which is arranged one or more pair of blades so positioned as to be acted upon by the water and caused to move longitudinally of the-frame. Connected to these blades are power transmitting means, and also means for shifting the position of the blades so as to engage the water for permitting the water to force the blades in a return movement, and at the same time actuate properly the power transmitting means.

In order that the invention may be more clearly understood an embodiment of the same is shown in the accompanying drawings, in which 1 indicates the framework preferably made from angle iron in which is mounted a plurality of blades 2 and 3. Blades 2 and 3 are formed identical in construction, and the associated parts are identical, so that the description of one will equally apply to the other, the only difference being that the same are set to operate at opposite angles, as clearly shown in Fig. 1. Each of the blades 2 is formed with journal members 4-4. These journal members project into reciprocating guides 5-5, and are pivoted therein. The guides 5-5 are each provided with anti-friction and guiding wheels 6 and 7. These guiding wheels are mounted to operate in guideways 8 and 9. By this arrangement the guides 5-5 may be freely moved back and forth, and consequently the journal members H are moved in a line back and forth. Blades 2 are continuously main tained at an angle different from a right angle to the guide 5-5, except when the blades are at their extreme movements, and are shifting their positions. This will cause the water traveling through the motor, as indicated by the arrow in Fig. 1, to act against all of the blades, and continuously move. the same. The set of blades 2 and 3 respectively are preferably not set to operate at an angle of 180 but at an angle different from 180, so that while the blades 2 are turning, and consequently have no power exerted thereon, the blades 3 will be receiving power which power will be communicated to the machine being operated, and to the blades 2 for continuing the shifting thereof until the same have arrived at their new position or angle. The motor is preferably provided on the sides with a covering 10 so that the water when once entering the motor will be compelled to pass entirely therethrough and operate the respective blades 2 and 3. It will be evident that either open face or edge of the motor may be pointed up-stream and the device will operate. Also if the stream should not have a sufiicient volume or movement to operate the motor as fast as desired a dam could be provided, or means for directing all or part of the stream into the motor.

The upper ends of the guides 5-5 have pivoted therein a shaft 11 to which is rigidly secured connecting rods 1212. The con necting rods 1212 are pivotally connected with the gear wheels 1313 from which power may be taken as desired. The gear wheels 1313 are rigidly secured to a shaft 14 which is mounted upon a suitable support 15 connected with the framework 1. The shaft 11 is pivotally mounted in the ends of-the guides 55, but has rigidly secured thereto a pair of blade shifting frames 16 and 17 at each end thereof; A pair of blade shifting frames, of course, are provided for each set of blades 2 and 3, and if for any reason it should be desired to have more than two sets of blades 2 and 3 there would be additional blade shifting frames. The frames 16 and 17 are provided with slots 18 and 19 respectively in which are mounted pins 20 and 21 which are preferably in the nature of bolts or thumb screws which will clamp the upper ends of the links 22 and 23 to the frames 16 and 17. This clamping arrangement is shown more clearly in. Fig. 4 in which the bolt 20 is shown provided wit-h an enlargement 24 and a nut 25. l/Vhen nut 25 is tightened the same will clamp bolt 20 firmly to frame 16, but will permit a free pivotal movement of link 22 which is j ournaled on the outer end of bolt 20, and is prevented from removal thereof by a suitable washer and cotter pin or other desired means. The links 22 and 23 eX- tend down to, and preferably shortly below the lowermost blade 2, and are preferably connected at 26 and 27 to blade connecting bars 28 and 29. Bars 28 and 29 are provided wit-h a plurality of apertures for accommodating pins 30 and 31 which are rigidly connected with the blades 2 and which project through the bars 28 and 29. These pins are loosely mounted in the bars so as to freely turn when the blades are shifting their posi tion or when the blades are being manually adjusted. It will be evident that there are links 22 and 23 on'each side of the blades 2, and consequently there will also be bars 28 and 29 on each side of the blades 2. By this arrangement when the blades 2 have moved to near their uppermost position, wrist pin 32 will be nearing what might be termed dead center, and passing from the right of wheel 13 to the left, and consequently tilting the connecting rod 12 at an opposite angle. This will, of course, tilt shaft 11 and all the frames 16 and 17 connected therewith. When the frames 16 and 17 are tilted at a difierent angle motion will be conveyed to used for operating the motor.

the blades 2, through links 22 and 23 and the bars 28 and '29 for shifting the angle of the blades. hen the blades are shifted in this manner the water entering in the direc tion of the arrow will move the blades in a reverse direction. If it should be desired to cause blades 2 to operate at a dilferent angle from those shown in the drawings, the bolts 20 and 21 are adjusted longitudinally of the frames 16 and 17 for causing the blades to operate at a greater or less angle as desired. Where the flow of water is comparatively slow but large in volume the blades are 1 preferably set at a considerable angle and the motor will give forth a considerable power but at a comparatively slow rate. If the blades are set at a greater angle and the flow of water is rapid though not of large volume, the motor will operate at a comparatively highrate of speed, but with a less power for each rotation of the wheel 13 than when moving slower under a high pressure. However, the higher rate of speed may be geared down and substantially the same power secured.

As shown in Fig. 1, there are arranged a plurality of water guards or guiding members 34at the front of the motor for controlling and guiding the water against the blades. Guards 34 are rigidly secured to pivotally mounted supporting shafts 35, each of which have rigidly connected therewith an arm 36. Each of the arms 36 has pivotally connected therewith at 37 a reciprocating link 38. Each of the links 38 carries a roller 39 andis provided with a slot 40 into which pin 41 projects. The respective pins 41 are mounted in the side plates 10, and project into the slots 40 for guiding the links 38 in their movement. The blades 2 carry a guide 42 which is inclined at 43 and 44. As shown in Fig. 5 guide 42 has secured thereto pins 45 mounted in bearings 46, which are fastened to the blade 2. Guide 42 is designed to engage rollers 39 and move the same back and forth. The first movement is to cause the respective rollers to shift their respective guards 34 for opening the same, and then hold the rollers in such a position as to hold the guard open until the blades 2 have passed, and then the beveled or inclined part 44 will actuate the respective rollers and cause the same to close guards 34. In this way no water can enter the motor except directly in front of the blades, and by this means a minimum amount of water may be Preferably the respective guards 34 are pivoted slightly off center so that when moved to a closed position the pressure of the water will hold said guards in a closed position until positively removed therefrom. I

It will be observed that just as the motor reverses the blades 2 carrying the guides will swing around pivots 4 and carry the said guides out in a direction toward plates 34. This action carries rollers 39 and consequently slotted links 38 in the same outward direction, which results in arms 36 and plates 34 being turned to a slight angle, just at the moment of the reversal. The links 38 and arms 36 are so proportioned and slot 40 is of such a length as to just accommodate this momentary outward movement.
